I tried the process of transforming map files .img in files to Mapsource.
I ask you to run “install.bat” and test.
We will try to solve any problem that may happen in this install (the 18079743.img file is missing; following the software used cGPSmapper).
Please, give me a feedback only if anything goes wrong; and just a “like” is enough if all goes right (useless or thanking posts are not allowed!!!). I can’t test it in my PC because it already has this maps installed. And I accept suggestions to improve the process to do this conversion (and will make this to other maps…); it’s only my first attempt...
All maps are already unlocked; however, suggest generating the file .unl using [Only registered and activated users can see links. ] and FID 2925 (use the Garmin WebUpdater to discover your “unit ID” and save in word to further refer). Also suggest add the another files; like JCV files,…
